There's something wild about Camila Cabello’s“Liar” music video. Maybe it’s the elephants dropping from the skies, or the flock of flamingos camped on her property. Or the dozens of identical cyclists who swamp her. Whatever, it’s hilarious and ridiculous. And it looks as expensive as her fiance's tastes.Directed by Dave Meyers, “Liar” sees Cabello play a range of characters for fun. As the story goes, she’s stuck with a rich douchebag, who she doesn’t really like, and she hates the restaurant he takes her to, and doesn’t dig his folks.But it's hard to decipher what's real and what’s a dream. She’s living a lie. But she does like the waiter, for real.
